INSTALLATION GUIDE
Disconnect and lock out all power sources during
installation and configuration.
If making connections to the meter through more than
one metallic conduit, use a bonding plate (Veris part
number AH11 or equivalent) to prevent electric shock.
1. Verify that the serial number on the meter matches the serial numbers on the
current transformers (CTs). These are calibrated as a set, and mixing transformers
with non-matching meters may damage the device when power is applied. The
meter’s serial number is printed on the label affixed to the inside of the front
cover, and the CT serial number is on the CT label. If using 100A CTs, serial number
matching does not apply.
2. Mount the meter.
3. Attach the CTs to the conductors. Local code requirements may require a mounting
bracket. For maximum accuracy, run the conductor through the center of the
current transformer window.
4.
Optional step, per NEC and local regulations:
Attach external fuses (not included
with the H81xx devices). Verify that the fuse rating is adequate for the applied
voltage, with a current rating of ½ Amp (T) slow blow. Select fuses with a fault
current rating that matches the power source rating.
